Practical to Investigate Diffusion and Osmosis Collect the following equipment: 1x beaker 1x length visking tubing 1x pipette 1x pair safety glasses Instructions – always wear safety glasses! 1. Fill your beaker ¾ full with water 2. Tie a knot in one end of your visking tubing 3. Using your pipette‚ transfer some concentrated sugar solution to the inside of the visking tubing‚ leaving enough space to tie a knot in the open end 4. Add a few drops of red food colouring to the inside of the visking

of dollars. Most of these resources‚ however‚ did not go into the theory of designing a bomb‚ as design was a relatively small part of the budget; rather‚ the money and manpower were needed to produce weapons-grade plutonium and uranium. Gaseous diffusion was‚ at the time‚ the most efficient way of separating the 235 U and 92 238 U isotopes.1 92 The question of why scientists entertained the idea of a uranium bomb at all is an intriguing one. Bohr had already demonstrated that uranium‚ when undergoing

Madden’s Crusades is an exposition of the crusades‚ which occurred during the Middle Ages. The Crusades were a series of military conflicts of a religious character. They remain a very important movement in human history‚ and are hard to understand‚ as they include several themes and they lasted for a long time (about two hundred years‚ and the author covers a period of about eight centuries in his chronological work). Religion is‚ of course‚ the most recurrent theme we think about the Crusades‚ but

Brian Toohey Biology Mrs. Heimforth 12/06/10 Diffuse the Osmosis Section 2: Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same

Cultural Identity and Cultural Rights “People need to see that‚ far from being an obstacle‚ the world’s diversity of languages‚ religions and traditions is a great treasure‚ affording us precious opportunities to recognize ourselves in others‚” Youssou N’Dour (Musician). I certainly believe that cultural diversity is one of the most important matters in society and that we should learn to acknowledge it. Unfortunately‚ we may be culturally diverse but we tend to forget about equality amongst

mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can affect the rate of diffusion‚ as a higher/lower temperature

the Ayyubid dynasty. Saladin was born 1138 in Tikrit‚ Iraq and died on 4 March 1193 in Damascus‚ Syria. Saladin was married to Ismat ad-Din Kahtun and had 7 sons. Saladin was a Muslim military and political leader who led Islamic Forces during the Crusades. He was raised in a Kurdish‚ Sunni‚ military family‚ he quickly rose the ranks within the Muslim society as second in charge to the Syrian-northern Mesopotamian military leader Nur al-din.

architecture‚ and the heavily ornamented style of music that came out of the renaissance. Today‚ the term ‘Baroque’ refers to a clearly definable genre of music which occurred between 1600-1750. In this essay‚ I will be talking about the socio-cultural influences on music during the baroque period‚ the philosophy of baroque composers‚ some famous and influential composers of the era‚ musical forms that came to define the baroque period‚ some characteristics of baroque music‚ and finally
